How to secure Ubuntu Guacamole Server with own Root CA signed SSL certificate?

Hi all,
I installed a Guacamole Server with Ubuntu 24.04LTS in our internal company network.
We are using Always-ON VPN and it should only be reachable from internal network.
All internal webservers in our company must be secured by internal certificate by our own ROOT CA.
Is there a way to secure the Ubuntu Guacamole Server by a SSL Certivicate from a internal ROOT CA (Active Directory Certivicate Services) to avoid the certificate error message in the browser when accessing via port 443 / https ?
Thanks in advance

I'm quite sure there is. Create the certificate in your ROOT CA or ask sys admin to do that, then install the certificate files so Guacamole can use them.
